Apogee Instruments MQ-650: Underwater ePAR Quantum Meter Bundled with AM-320 Water Submersible Sensor Wand Includes Apogee Instruments Neoprene Case
  • FOR SCIENTISTS & SERIOUS GROWERS - Designed by world-renowned crop physiologist, Bruce Bugbee, PhD, the MQ-650 ePAR (extended-range PAR) underwater quantum meter is the premium tool of choice among leading scientists and serious growers for accurately measuring the photosynthetically active radiation (PAR) underwater. Package includes an AM-320 three-piece 3' corrosion-resistant wand and an Apogee neoprene carrying case.
  • MEASURING PAR IS CRITICAL - An accurate PAR meter is critical for measuring the intensity of light used in the precision growing of plants and other photosynthetic organisms in greenhouses, growth chambers, farms, gardens, aquariums, and additional agricultural systems. Our underwater quantum meters are specifically designed to measure the intensity of light underwater for biological, chemical, and physical processes in natural waters and aquariums.
  • UNDERWATER ACCURACY - Underwater PAR measurements can read low when a quantum sensor is calibrated for air. The MQ-510 applies an immersion effect correction factor to get instant, accurate measurements underwater. Precisely measures and combines the intensity of all photons between 400 and 700 nm to give a single PAR reading in µmol m-2 s-1 within 5 % uncertainty. Unlike hobby-grade PAR meters, our meter has a stable, accurate calibration with an accuracy drift rate of less than 2% per year.
  • QUALITY ePAR METER - Unlike cheaper LUX or footcandle sensors which are sometimes marketed as grow light meters, but are meant for measuring light for human vision, our meters feature a laboratory-grade ePPFD (extended photosynthetic photon flux density)optical detector precisely calibrated to measure the light intensity in µmol m-2 s-1 of the specific color wavelengths (including far-red) emitted by LEDs, HPS, MH, sunlight, and other light sources utilized by plants/corals etc. for photosynthesis.
  • NEW ePAR RANGE - Laboratory-grade measurement of the newly defined 400-750 nm ePAR has been found to be photosynthetically active beyond the traditional 400-700 nm (PAR). Much of the transformative work to define the ePAR range was conducted by Dr. Shuyang Zhen and Dr. Bruce Bugbee. The MQ-610 can accurately measure far-red photons (700-750 nm), found in many next-generation LED fixtures, the sun, and other light sources, which cannot be measured by traditional PAR meters.

Quantum Sensor PAR Meter Full-Spectrum PPFD Tester for Accurate Light Measurement Indoor and Outdoor Plant Photosynthetic Activity
  • 🌱PPFD Measurement: Measures Photosynthetic Photon Flux Density (PPFD) within a range of 0 to 5000 μmol/m²/sec. Measures wavelengths within the range of 400±10nm to 700±10nm, covering the essential spectrum for photosynthesis. Features a spacious screen display for effortless reading of measurements, ensuring clarity and convenience. Provides MAX/MIN/AVG data functionality, enabling thorough analysis of measured values.
  • 🌱3 TYPES OF MEASUREMENTS: 1)Dynamic Measurements: As you move the meter over an area, dynamic measurements are taken every second. Dynamic measurements continue to be made until you either press HOLD or turn the unit off. Dynamic measurements are stored in an internal buffer and used to report AVE (average), MAX (maximum), and MIN (minimum) dynamic measurements. 2)Hold Measurement: When HOLD is pressed, the word “HOLD” is displayed, and additional dynamic measurements are no longer made. 3)Logged Measurements: Up to 100 measurements may be stored in a data log at indexes 001 through 100. To log any dynamic measurement, simply press the UP/LOG button.
  • 🌱ADDITIONAL FUNCTIONS: Introduces four modes, each with distinct capabilities: AVEC: measures PPFD every second and report the average measurement, REC: measures PPFD every second and reports the data logged, CAL: zero point , and RES: reset the unit and clear the log. (Pls note: When you first turn the unit on, it starts in AVE mode where the meter takes a PFFD measurement every second. This enables you to immediately move the meter over an area to determine the average PPFD).
  • 🌱FLEXIBLE PERFORMANCE: Features a tripod socket for stable mounting during measurements, ensuring accuracy and convenience. Please note: Can’t leave the unit on a tripod to record average light during a period, because the unit automatically shuts off after 3 minutes when no buttons are pressed.
  • 🌱 Data Recording and Live Display: Enables the storage of up to 100 measured values, supporting thorough data accumulation and scrutiny. Offers a live display of the most recent four recorded data points, facilitating swift monitoring and analysis. To see additional logged measurements, press the MODE button until REC is displayed. After a brief delay the word REC will blink. Next, press the HOLD. This results in index 001 blinking at the top center of the display to the right of REC and the measurement stored at index 001 to be shown in the center of the display.
